This is a 41-50 litre pack that’s designed to keep the weight down. The parts that need to be sturdy are just that, while other sections are nice and light. Even the clips are designed to reduce weight, and the walking pole straps can be removed. Pockets are limited to an internal and an external pocket in the lid, while wand pockets on the sides and elastic on the lid will allow extras such as fleeces and water to be kept handy. The snow lock is fairly deep with the added benefit of being compressible. The shape is nice and slim too, ensuring only the colour and the design will make you stand out. The Trail tested capacity matched the manufacturer’s claims to the litre. But though the main pack is a great shape, as soon as you pack into the snow-lock extension the lid bulges badly. While the shoulder straps have been designed to be lightweight, this unfortunately makes them dig in and feel rather uncomfortable to wear.
